Preheat oven to 350F. Grease and line 2 9” cake tins.
Tear the kale leaves into bite-sized pieces and boil or steam for a few minutes until tender. Refresh in cold water, drain and puree (it will still be a bit stringy). Set aside.
Beat the eggs, oil, vanilla, applesauce and sugar together well. Beat in the kale puree and grated apple. Sift in the flour, baking powder and salt and gently combine.
Pour into the prepared tins and bake for 30 minutes or until an inserted skewer comes out clean. Cool for 2 minutes in the tins and then turn onto a wire rack to cool completely.
Apple Icing:
Sift the icing sugar into a bowl, add the other ingredients and mix until smooth.
Store in the fridge until ready to use. Frost the cooled cake.
Recipe Notes
If you don’t have applesauce, just peel, core and slice some apples, steam until soft and puree.
